CVE-2015-0291 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The sigalgs implementation in t1_lib.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by using an invalid signature_algorithms extension in the ClientHello message during a renegotiation.
CVE-2016-2181 2 Openssl, Oracle 2 Openssl, Linux 2025-04-12 5.0 MEDIUM 7.5 HIGH
The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial of service (false-positive packet drops) via spoofed DTLS records, related to rec_layer_d1.c and ssl3_record.c.
CVE-2015-0208 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The ASN.1 signature-verification implementation in the rsa_item_verify function in crypto/rsa/rsa_ameth.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted RSA PSS parameters to an endpoint that uses the certificate-verification feature.
CVE-2016-2180 2 Openssl, Oracle 2 Openssl, Linux 2025-04-12 5.0 MEDIUM 7.5 HIGH
The TS_OBJ_print_bio function in crypto/ts/ts_lib.c in the X.509 Public Key Infrastructure Time-Stamp Protocol (TSP) implementation in OpenSSL through 1.0.2h allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted time-stamp file that is mishandled by the "openssl ts" command.
CVE-2014-3566 11 Apple, Debian, Fedoraproject and 8 more 20 Mac Os X, Debian Linux, Fedora and 17 more 2025-04-12 4.3 MEDIUM 3.4 LOW
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.
CVE-2014-3567 1 Openssl 1 Openssl 2025-04-12 7.1 HIGH N/A
Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure.
CVE-2014-3506 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via crafted DTLS handshake messages that trigger memory allocations corresponding to large length values.
CVE-2015-1792 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The do_free_upto function in crypto/cms/cms_smime.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (infinite loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized X.660 OID for a hash function.
CVE-2015-1791 1 Openssl 1 Openssl 2025-04-12 6.8 MEDIUM N/A
Race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b, when used for a multi-threaded client, allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been obtained earlier.
CVE-2015-0285 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The ssl3_client_hello function in s3_clnt.c in OpenSSL 1.0.2 before 1.0.2a does not ensure that the PRNG is seeded before proceeding with a handshake, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by sniffing the network and then conducting a brute-force attack.
CVE-2014-3512 1 Openssl 1 Openssl 2025-04-12 7.5 HIGH N/A
Multiple buffer overflows in crypto/srp/srp_lib.c in the SRP implementation in OpenSSL 1.0.1 before 1.0.1i allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid SRP (1) g, (2) A, or (3) B parameter.
CVE-2016-2842 1 Openssl 1 Openssl 2025-04-12 10.0 HIGH 9.8 CRITICAL
The doapr_outch function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not verify that a certain memory allocation succeeds, which allows remote attackers to cause a denial of service (out-of-bounds write or memory consumption) or possibly have unspecified other impact via a long string, as demonstrated by a large amount of ASN.1 data, a different vulnerability than CVE-2016-0799.
CVE-2016-0705 5 Canonical, Debian, Google and 2 more 5 Ubuntu Linux, Debian Linux, Android and 2 more 2025-04-12 10.0 HIGH 9.8 CRITICAL
Double free vulnerability in the dsa_priv_decode function in crypto/dsa/dsa_ameth.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a malformed DSA private key.
CVE-2015-1793 2 Openssl, Oracle 4 Openssl, Jd Edwards Enterpriseone Tools, Opus 10g Ethernet Switch Family and 1 more 2025-04-12 6.4 MEDIUM 6.5 MEDIUM
The X509_verify_cert function in crypto/x509/x509_vfy.c in OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, and 1.0.2c does not properly process X.509 Basic Constraints cA values during identification of alternative certificate chains, which allows remote attackers to spoof a Certification Authority role and trigger unintended certificate verifications via a valid leaf certificate.
CVE-2016-6302 2 Openssl, Oracle 3 Openssl, Linux, Solaris 2025-04-12 5.0 MEDIUM 7.5 HIGH
The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before 1.1.0 does not consider the HMAC size during validation of the ticket length, which allows remote attackers to cause a denial of service via a ticket that is too short.
CVE-2010-5298 4 Fedoraproject, Mariadb, Openssl and 1 more 7 Fedora, Mariadb, Openssl and 4 more 2025-04-12 4.0 MEDIUM N/A
Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment.
CVE-2014-3511 1 Openssl 1 Openssl 2025-04-12 4.3 MEDIUM N/A
The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue.
CVE-2016-7052 3 Nodejs, Novell, Openssl 3 Node.js, Suse Linux Enterprise Module For Web Scripting, Openssl 2025-04-12 5.0 MEDIUM 7.5 HIGH
crypto/x509/x509_vfy.c in OpenSSL 1.0.2i allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) by triggering a CRL operation.
CVE-2015-0287 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse.
CVE-2015-0206 1 Openssl 1 Openssl 2025-04-12 5.0 MEDIUM N/A
Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate records for the next epoch, leading to failure of replay detection.
